Abstract
Abstract A knock down chair assembly wherein a plurality of elongated support members are packaged in a tubular housing together with a flexible seat member wrapped with the support members. The tubular housing has a plurality of oppositely aligned mounting apertures which can receive the elongated support members in assembling the chair. Two of the support members operate as arm and seat supports and at least three support members operate as leg supports. A tie element may be used to join the various support members by being passed through openings in one of the ends of the support members.
